Surface Reaction
Hello guys,
I wanna simulate a surface reaction in FLUENT. However, the details of volumetric reaction for gas-phase and heterogeneous reaction are not in the literature. So, I am wondering if I can create this surface reaction by myself, introducing the Arrhenius parameters, activation energy etc. In other words, I would like to know whether or not I am able to create a reaction based on the global reaction? (without intermediate reactions) Thanks for your help Babak |

Dear Babak, I had problem in simulation of surface reaction in FLUENT, for mixtures that I didn't have the details of chemistry mechanism. Did you check in CHEMKIN? In my case, CHEMKIN also doesn't provide that information. Also, I investigated a lot in literature but no gain. Is your problem similar to mine? Please share your experience with me if you got any success. |

Hello Parisa, Thanks for reading my post. Yes, seems my problem is partially similar to yours. Yes, I did check with CHEMKIN and this surface reaction is not covered in CHEMKIN as well. Like your case :) For sure I will keep you posted if I found a way to solve that. |

Any update? |
I suppose there's no any remarkable problem in setting a volumetric reaction both in gas or liquid phase. Regarding to heterogeneous reaction, I think you should use UDF for this purpose. Concerning to the second questions, you don't need to use intermediate reactions, only global would be OK. The procedure to set a Arrhenius reaction is simple and straightforward, you just need to have activation energy and pre-exponential factor and reactions exponent. There is a good tutorial about this. I think, CVD (Chemical Vapor Deposition) tutorial is good enough to help you to find your way to proceed further.
Good luck |
